Apple CEO Tim Cook announced, "We pay all the taxes we owe - every single dollar." Whole Foods co-founder John Mackey supported the iPhone maker, saying "It's not Apple's fault that they're seeking to avoid paying taxes. They're not lying, cheating or stealing. They're following the rules that were created by governments. If the government doesn't like the rules, they can change them."

Mackey didn't mention that changing the tax rules is a specialty of big business. As is flouting the tax rules. The following four tales of corporate malfeasance are particularly disturbing.
